SPECIFICATION forming part of Letters datent no. 660,278, dated October 23, 1900.

Application filed A ril 16, 1900;

To all whom it may concern: Be it known that I, EDWARD SMITH, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented new and useful Improvements in Dry-Pans, of which the following is a specification.

My invention relates to improvements in, dry-pans for working clay or shale; and it consists, primarily, in providing a plowshare with a steam-chest provided with one or more vents and having a suitable flexible connec-' tion with the steam-supply, whereby steam is sprayed into the clay while it is being crushed and pulverized in the dry-pan, as will be hereinafter more fully described and claimed.

Figure 1 is a perspective view of a dry-pan, illustrating my invention. Fig. 2 is a rear view of the plow. Fig. 3 is a front view of the plow. Fig. 4 is a perspective view of a section of the forward end of the plow. Fig. 5 is a longitudinal sectional view through X X. Fig. 6 is a vertical sectional View through Y Y.

In the accompanying drawingssimilar letters of reference refer to similar parts.

A represents the frame or housing of the dry-pan, which may be of any desired form and is provided with a cross-head 0, having journaled therein the upright shaft D, which carries the dry-pan d, and is provided with perforated plates d, which permit the pulverized clay to pass therethrough onto the floor. Mounted in sliding boxes E and E is the roller-shaft e, carrying the rollers e and 6 For the purpose of driving the upright shaft carrying the pan I have shown the bevel gear 01 mounted upon the upright shaft D, meshing with the bevel-pinion f, mounted upon the counter-shaft F, which carries the belt-pulley f. a

lhe features of construction above described may be varied or changed and are of the common and well-known form of construction.

My invention consists in the following spesists of the plowshare it, provided at its upper edge with longitudinal slotted apertures Serial No. 12,994. (N6 time.)

-h and at its lower edge from front to rear with plate hflprovided with apertures 7?, by means of which it is bolted inadjustment to the swivel-plate g on the cross-rail G. For the purpose of adjusting the plowshare up or down or forward or backward upon the swivel-plate I have provided vertical openings h in the swivel-plate, by means of which the plowshare and plate may be bolted together at any desired adjustment. The steam chest or box it consists of a cast or malleable iron box, open upon one face and end and adapted to be bolted to the plowshare by means of the bolts h At the forward end I provide a screw-threaded nipple h to receive a corresponding screw-threaded coupling attached to the hose I, which communicates with the steam-supply pipe.

In operation the clay or shale to be pulverized is sho'veled into the dry-pan forward of the plow, when the upright shaft D is caused to revolve, carrying'with it the pan, which causes the rollers to revolve, crushing the clay or shale. The steam is carried from the steam-supply through the flexible tube I into the steam-chest h thence through the steam- 8o orifices k on the face of the plowshare and the steam-orifice h on the end-of the steamchest, thus moistening and heating the clay,

rendering it more plastic and more easily pulverized. It is especially desirable in wintertime to thus apply steam, because the shale or clay isfrequently frozen into solid masses which it is exceedingly difficult topulverize without thus heating and moistening. In sum- 'mer-.time water can be similarly supplied 9o through the same appliances, and thus prevent the raising of dust, which becomes so objectionable in operating this class ofmachinery. r

Various changes and modifications may be made in the details of construction without departing from the spirit of my invention, which consists,primarily,inprovidingasteam orwater chest adapted to be attached to'the plow of the dry-pan, provided with suitable jets and having a flexible connection with the steam or water supply.

Having thus fully described my invention, what I desire to secure and claim by Letters Patent is 1. The combination in a dry-pan, of a plow 5 with a steam or Water chest attached thereto,

forth.

3. A plow for dry-pans, consisting of an adtially as described and for the purpose set justable swivel-plate carrying a plowshare, a steam or water chest attached to the plowshare, and provided with discharge-orifices, and a flexible steam or water-supply pipe, substantially as described and for the purpose set forth.

4:. A plowshare for dry pans, provided I with a steam or water chest having dischargeorifices, substantially as described and for the purpose set forth. I

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
